Abstract
Increased plasma cholesterol and/or triglyceride concentration in the fasted state is a relatively common abnormality detected in dogs, and less frequently in feline patients, and is termed hyperlipidaemia…This chapter reviews normal lipid metabolism and the clinical assessment of lipid/lipoprotein disorders in dogs and cats. The following topics are addresssed: Normal lipid metabolism, hyperlipidaemia, hypolipidaemia, investigation of hyperlipidaemia and laboratory effects of hyperlipidaemia. The chapter includes case examples.
